Brendan Doherty is getting some high-profile help with his congressional campaign.

U.S. Sen. Scott Brown, the Massachusetts Republican who shocked the political world in 2010 when he won the late Ted Kennedy’s old seat, will be in Rhode Island next month to headline a Doherty fundraiser, the campaign said.

Brown will be the special guest at a July 2 event to raise money for Doherty at the Metacomet Country Club in East Providence. Suggested contributions start at $100 and go up to $2,500. The Reggie Centracchio Quintet will provide the music.

Doherty had a strong fundraising year in 2011 after entering the race to unseat freshman Democrat David Cicilline before he lost ground in the first quarter of 2012. As of March 31, Cicilline had $701,249 on hand while Doherty had $559,645. Doherty doesn’t face a primary challenger, unlike Cicilline, and the Republican had a 15-point lead in a February WPRI 12 poll.

Brown, who lives in nearby Wrentham and has expressed a fondness for Federal Hill cuisine, is locked in his own tight U.S. Senate reelection race in Massachusetts against Democrat Elizabeth Warren. The Real Clear Politics polling average gives him a 0.3-point lead over the challenger.
